1.) There are many media companies in Taiwan that have taken subsidies/investments from the Chinese government. For example, the richest Taiwanese, Tsai eng-meng, currently lives in Shanghai, and owns many tv stations and newspapers in Taiwan. Many of these tv stations are watched by the older generations, and a lot of the channels are politics focused. Thus these channels usually have a pro-China angle on them: how well China is doing economically, and ignores any sort of xinjiang/Hong Kong/trade war problems/economic slowdowns/human rights issues China has. I shuddered when an older relative told me that the tv show had told him that concentration camps for Uighurs are ok because it keeps the peace.
And don’t think this is restricted to Taiwan. China has spread its media influence to other democratic countries in the world as well.
2.) hacking politicians. The pro-China presidential candidate, Han-Kuo-yu, was a literal unknown 6 months before the election for city of kaoshung. However, thanks to a (purported) digital influence campaign by Chinese hackers, he won the election. Then he declared to run for president, without having accomplished much of anything for the city. This sort of thing could also happen to US, in that China could interfere in the 2020 election.
